Abstract
In this work, the crimp properties of PTT/PET bicomponent filament with different component ratios were investigated. The results show that, after boiling water treatment for 15 minutes, the crimpability of 50/50 component ratio is superior to that of 40/60 and 60/40 component ratio. Heat treatment can realize the shrinkage difference of the two components in a biocomponent filament and enable the biocomponent filament to have good crimpability and bulkiness. In addition, different heat treatments, heat treatment time and heat treatment temperature can also bring different crimp effects to the biocomponent filaments.
